CVE-2025-14047 identifies a missing authorization vulnerability (CWE-862) in the WordPress plugin 'User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration' developed by tareq1988. The vulnerability exists in the 'Frontend_Form_Ajax::submit_post' function, which lacks proper capability checks before processing frontend post submissions. This flaw allows unauthenticated attackers to invoke this function and delete attachments arbitrarily, leading to unauthorized data loss. The vulnerability affects all plugin versions up to 4.2.4. The attack vector is remote and requires no authentication or user interaction, making it relatively easy to exploit. The CVSS v3.1 base score of 5.3 reflects a medium severity, with the impact primarily on data integrity (unauthorized deletion of attachments) and no direct impact on confidentiality or availability. No patches have been linked yet, and no known exploits are reported in the wild as of the published date. The plugin is commonly used on WordPress sites to enable frontend user content submission, membership management, and user registration, making it a critical component for websites relying on user-generated content. The lack of authorization checks in this function represents a significant security oversight that could be leveraged by attackers to disrupt content integrity and potentially damage website reputation or user trust.

For European organizations, this vulnerability can lead to unauthorized deletion of attachments on WordPress sites using the affected plugin, compromising data integrity and potentially disrupting business operations reliant on user-generated content. Organizations in sectors such as e-commerce, online communities, membership sites, and content platforms are particularly vulnerable. The loss of attachments could include critical documents, images, or other media, affecting customer experience and operational workflows. Additionally, exploitation by unauthenticated attackers increases the risk of automated or opportunistic attacks, potentially leading to reputational damage and increased incident response costs. While availability and confidentiality are not directly impacted, the integrity breach could indirectly affect trust and compliance with data protection regulations such as GDPR if user data or content is lost or manipulated. The medium severity rating suggests a moderate but non-negligible risk, especially for high-traffic or business-critical websites.

1. Monitor official plugin channels and security advisories for patches addressing CVE-2025-14047 and apply updates promptly once available. 2. Until patches are released, consider disabling or restricting the plugin's frontend post submission functionality to trusted users only, if possible. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the 'submit_post' AJAX endpoint. 4. Conduct regular backups of website content, including attachments, to enable rapid recovery from unauthorized deletions. 5. Audit user roles and permissions within WordPress to minimize exposure and ensure least privilege principles. 6. Employ intrusion detection systems (IDS) to monitor for anomalous activity related to attachment deletion. 7. Educate site administrators about the vulnerability and encourage vigilance for unusual content loss or site behavior. 8. Consider alternative plugins with verified security postures if immediate mitigation is required and patching is delayed.
